Definitions

  • the invention relates to a device for embossing foil printing in a coating module, which includes a device for transferring image-forming layers from a carrier foil to printed sheets.
  • a printing material and a printing apparatus using this material are described.
  • a sheet-processing machine which has a feeder and a boom, between two units printing units and a coating unit are arranged.
  • an adhesive pattern is applied by means of the planographic printing process.
  • This adhesive pattern is applied in a cold printing process and has a specific imaging subject.
  • a film guide is provided, in which a film strip or a film is passed through a film roll between the impression cylinder and transfer cylinder.
  • the foil strip is rewound on the outlet side after leaving the coating unit.
  • the transfer film has a carrier layer on which imaging layers such as metallic layers, for example of aluminum, can be applied.
  • each sheet When printing sheets are transported through the printing unit, each sheet is provided with an adhesive pattern and associated with the sheet material.
  • the downwardly lying metallic layer enters into a close connection with the areas provided with adhesive on the printed sheet.
  • the metallic layer adheres only in the area provided with the adhesive pattern. The print sheet is laid out in the coated state.
  • a device for embossed foil printing known.
  • a paint module of a sheet-fed printing machine is used as a unit for the use of a film transfer module.
  • the film transfer module contains all elements for the film transfer and is therefore difficult to access or can only be used for smaller rolls of film.
  • the object of the invention is therefore to provide a device by means of which a flexible use of a printing machine is made possible when using the stamping foil printing.
  • the transfer film in at least one film transfer module which is preferably arranged downstream of at least one paint module of a coating machine, brought into contact on a counter-pressure cylinder by a transfer cylinder with the printing material.
  • the coating unit is preferably placed at the end of the machine. This achieves a particularly simple machine configuration.
  • the film transfer module can be provided in conjunction with a paint module and a printing unit, so that even more difficult coating work can be carried out.
  • the film transfer module can also be connected to a printing unit designed as a sheet transport unit according to a paint module used for the adhesive application.
  • a printing unit designed as a sheet transport unit according to a paint module used for the adhesive application.
  • a film transfer module F is preceded by a paint module L directly.
  • the paint module L in turn, a printing unit D can be arranged directly upstream.
  • a recessed blanket or a flexographic printing is fixed on a forme cylinder 11 of the film transfer module F.
  • the paint module functions in this embodiment as an applicator for adhesive.
  • a chamber doctor blade system as metering system 13 thus serves to meter the adhesive via a screen or applicator roller 13 and the forme cylinder 11 on the printing material.
  • the printing material with adhesive application is fed to the downstream coating module in the form of the film transfer module F.
  • the forme cylinder serves as a transfer cylinder 21 for transfer film 24.
  • the transfer cylinder 21 is assigned at least the film supply roll 22 for fresh transfer film 24 and the film collection roll 23 for used transfer film.
  • the transfer cylinder 21 transmits in a transfer nip 6 between the transfer cylinders 21 and a counter-pressure cylinder 4, the image-forming layer of the transfer sheet 24 on the fixed in the gripper closure on the impression cylinder 4 substrate.
  • the transfer cylinder 21 on the impression cylinder 4 downstream of a calender roll 31 in the conveying direction may be embodied as an embossing roll.
  • a first layer of adhesive can be applied virtually as a basecoat in a printing unit D upstream of the paint module L.
  • the film supply roll 22 is assigned to the respective film transfer module F on the side of the sheet feed.
  • the film supply roll 22 has a rotary drive.
  • the rotary drive is required for the continuous controlled feeding of the unused film web 24 of the transfer film to the film transfer module F and is therefore controllable.
  • the used film web 24 is wound on a film collecting roll 23.
  • a drive is provided for the optimized production, which is controllable.
  • tension rollers 25 may be provided in the region of the film guide. The tension rollers 25 are arranged adjacent to the transfer cylinder 21 with respect to the supply and removal of the film web 24 to and from the transfer nip 6. By means of such tensioning rollers 25, the film web 24 of the transfer film can be held in such a secure position relative to the transfer cylinder 21.
  • the tension rollers 25 are arranged in the vicinity of the transfer nip 6 such that the film web 24 is guided approximately tangentially to the surface of the transfer cylinder 21 in the transfer nip 6.
  • the thus tangential guidance of the film web 24 reduces the friction conditions between the film web 24 and transfer cylinder 21 by a far-reaching minimization of the contact surface between the film web 24 and the surface of the transfer cylinder 21st
  • FIG. 2 shows the basic version of a coating machine. It has an investor AN with an investor stack ANS. In the investor AN the required for the printing material supply to the coating machine and known devices are integrated.
  • a paint module L with a metering device for a coating medium is provided to apply the adhesive.
  • a film transfer module F is provided, in which the stamping foil printing is carried out.
  • the film transfer module F obviously has the same basic configuration as the paint module L.
  • a boom AU is still provided, in which the coated printing sheets can be stacked on a delivery stack AUS.
  • embossed foil prints can be produced in the so-called offline mode, without a press being restricted in its function.
  • embossing film layer comes to lie advantageously on the surface of the sheet and thus has a good gloss effect.
  • FIG. 3 shows a modified version of a coating machine according to FIG. 2. It also has a feeder AN and a boom AU. Herein, however, a paint module L for adhesive application downstream of a printing unit D.
  • a film transfer module F is again provided, in which the stamping foil printing is carried out.
  • This coating machine allows printing sheets to be coated by embossing foil printing, e.g. to pretreat in the printing unit D designed as an offset printing unit. This may be important when processing precoated or printed signatures whose surface must be protected or prepared for embossing foil coating. Likewise, a pre-coating can be provided on a raw sheet of possibly highly absorbent material for improved adhesive acceptance.
  • process steps can be carried out both as printing, as well as coating and mechanical processing operations.
  • FIG. 4 shows a further modified version of a coating machine.
  • This embodiment like the embodiment according to FIG. 3, has a feeder AN, a delivery arm AU, a coating module L for the application of adhesive, a printing unit D and a film transfer module F.
  • the printing unit D is designed as a carrier for film rolls 22, 23.
  • the printing unit is designed for this purpose without ink or dampening unit, while the sheet guiding functions are completely provided.
  • the transfer film 24 is guided as described by the film roll 22 to the film transfer module F and from there back to the film roll 23.
  • the arrangement is so very compact and allows the inclusion of larger film rolls than in the variants of Fig. 2 and 3 is possible. Likewise, the handling of the film is solved both ergonomically in the exchange of roles and when retracting the film web in the film transfer module F.
  • the printing unit D By means of the printing unit D intermediate steps can be made after the adhesive application. In this case, drying operations or mechanical treatment of the sheet come into question.
  • the printing unit D is to do with devices provided for drying or prepared for receiving devices for the mechanical treatment of sheets.
  • FIG. 5 finally, a further version of a coating machine based on the embodiment of FIG. 2 is shown.
  • This embodiment has a feeder AN, a boom AU, a paint module L for the adhesive application, downstream of this a film transfer module F and this downstream of a further paint module L on.
  • a printing material in offline operation that is decoupled from a printing press, be provided with a stamping foil and in the subsequent process stage with a further coating.
  • additional coatings are gloss coatings, protective coatings or coatings with color effects in question.
  • the surface of the printing material can be provided with mechanically generated or layered jobs generated and profiling effect.
